About part number 31655538

A headlight control unit module manages the power supply and electronic signals for the vehicle's LED headlamp system. Connected directly to the main lighting loom and the headlamp assembly, it regulates functions such as beam height, daytime running lights, and automatic dipping. When operating correctly, the driver enjoys consistent road illumination, correct beam patterns, and no lighting warning messages on the dashboard.

To ensure this component is correct for your vehicle, check the part number printed on your original unit. You will usually find the part number 31655538 stamped or printed on a label on the metal casing or plastic housing of the module. Matching this exact number with the reference on your existing part is the only way to confirm correct fitment.

These electronic modules are usually replaced after failing due to internal circuit faults or water ingress into the headlamp housing. When swapping this component, a person replacing it often needs replacement mounting screws, fresh sealing gaskets, or a new headlamp rear cover to prevent moisture from damaging the replacement unit.
